Abstract: ABSTRACT:       It is necessary in many heat treatment processes conducted in open systems to maintain a given partial pressure of a volatile component of a material being treated, and it is desirable to conserve this volatile component, both on account of cost and in the case of components such as mercury, toxicity.  A controlled unsaturated vapour pressure of a volatile liquid 28 may be produced in a tube 3 by passing stream of a carrier gas through a vapouriser 4 containing the liquid 28 at a temperature Ts, passing the mixture of the carrier gas and vapour of the liquid 28 through a tube 3 containing material 29 to be treated, which material 29 is at a temperature Tt.  the mixture of the carrier gas and vapour of the liquid 28 is then passed to a condenser 6 from which the carrier gas is vented to waste, and the vapour of the liquid 28 is condensed at a tempera-ture Tc in the condenser 6.  Tt>Ts>Tc.  The condensate passes from the condenser 6 to the vapouriser 4 through a tube 12, and the liquid 28 fills a cross-section of a length of the tube 12.

Abstract: A collating apparatus having a collating unit, a perforating unit and a fan-folding unit, all gear driven by a single main drive gear, and having a gear assembly driven by the drive gear which includes a gear having an adjustable rotational eccentricity and an adjustable phase of eccentricity relative to the other gears. In a preferred embodiment, the adjustable gear includes an inner hub mounted on a rotatable shaft, an intermediate hub having an eccentric more rotatably receiving the inner hub, a gear ring having an eccentric bore rotatably receiving the intermediate hub and a clamp bar attached to the gear ring and to the shaft. The bar includes an adjustment mechanism for varying the orientation of the gear ring, intermediate hub and inner hub relative to each other. By adjusting the rotational eccentricity of the gear ring and the phase of the eccentricity, the adjustable gear can compensate for eccentricities inherent in other gears of the apparatus so that the collating, perforating and folding units operate synchronously.

Abstract: INTAKE MANIFOLD FOR INTERNAL COMBUSTION ENGINE HAVING EXHAUST GAS RECIRCULATION SYSTEM               ABSTRACT OF THE DISCLOSURE     An intake manifold (2) for an internal combustion engine equipped with an exhaust gas recirculation (EGR) system for recirculating a part of the exhaust gas to the intake system, having a V-shaped rib (13) formed on the inner surface thereof with the vertex (13a) directed upstream with respect to the flow of the intake air. The V-shaped rib is positioned upstream of the EGR gas outlet (10) of the EGR system so that oil contained in blow-by gas supplied by a positive crankcase ventilation (PCV) system or charged-air supplied by a turbocharger into the intake manifold (2) does not flow into the EGR gas outlet (10), but flows away from the EGR gas out-let (10).  Therefore, the deposition of sludge around the EGR gas outlet (10) is prevented and a sufficient EGR rate is secured.

Abstract: ABSTRACT OF THE DISCLOSURE:   A triple wall factory built thermally balanced on demand air flow metal chimney system in which the chimney sections are formed with an insulation chamber filled with insulation material which surrounds the chimney flue and an air passage chamber surrounding the insulation chamber.  A negligible amount of cooling air flows upwardly through the air passage chamber during normal operation of the chimney.  The air flow is separated from the inner flue by the insulating blanket.  This allows the flue to maintain the proper elevated temperatures to resist creosote deposits.  During periods of sustained high temperature operation or creosote fire episodes, substantial on demand cooling air flows upwardly through the air passage chamber drawing off heat from the inner flue and the outer wall.

Primary air ports surround the nozzle and include means for progressively increasing swirl of the primary air as radial distance from the nozzle increases and for adjusting the location of flame origin.  Metering of secondary air and adjustment of its direction of swirl are both accomplished rearward of the secondary air outlet, the primary air assembly moving rearwardly to increase the secondary air as firing rate rises.  A simple metal, frusto-conical flame holder is secured to and spaced forwardly of the burner head.

Abstract: Abstract of the Invention This device includes a water container (1) with a pump (8), an operating button (4) and a spray nozzle (5). A second container (2) holds a refrigerant which is released through a second spray nozzle (7) by pressing on a second button (24).  As a first aid measure, a film of water is first sprayed on the burn wound and then is frozen by means of the refrigerant.  In this way, an immediate and drastic reduction in pain is achieved.  Since the heat is rapidly and effec-tively dissipated from the injured tissue, substantially fewer burn toxins are formed so the healing prospects are greatly improved.  The subsequent scar tissue formation on the wound is much better from a cosmetic standpoint.  This device may be constructed in a small and handy form and therefore can be kept ready to use wherever there is the risk of burn and scald wounds.
